I have been lap swimming daily for decades. Recently the pool in which I currently swim developed an algae problem. They were shocking it daily and adding algaecide without telling the swimmers. Before I knew they were doing this, I was using vaseline as a barrier to combat my chlorine induced dermatitis. It didn't work. After the pool was corrected, I returned to swimming, but I was having the same reaction. After finding Trihard, I am not having the same reaction. I am using the wash and the lotion.
I have discovered that the vaseline and vegetable glycerin I was using as a barrier was actually causing an enhanced reaction. Now what I do is swim normally, apply the wash directly after swimming and let it stay on my body for two minutes. Then I dry completely before applying the lotion. The difference is amazing.
My only complaint is that I wish there was a larger, bulk size for the lotion. I use an entire tube in about two weeks, so it is very expensive for my purposes.
